The sturdy, stable instrument is equipped with a built-in industrial PC and a touchscreen. It is available in three versions: 1-head (top side), 1-head (underside), or 2-head (top and underside).

Test description
The sample is placed below the measuring head. On pushing the start button, the 10 kg weight lowers onto the sample and helps to hold it tight to the glass plate. The built-in vacuum pump evacuates the selected tank to a vacuum of -50.7 kPa. Dependent on the surface roughness of the sample, atmospheric air is drawn in between the glass plate and the sample. The time taken for the vacuum to reach -48.0 kPa (res. 29.3 kPa) is displayed in BEKK seconds. Ten seconds after the test has started a preview is displayed to give an estimation of the result in advance.
